The syscall was added to 4.11, and the warning will be resolved as soon
as all architectures add it to their tables.

I just resent my fix for the second time

A new regresssion as of today, won't be able to look myself, but this
should be trivial to address.

A new regression from the end of the merge window, also present in mainline.
I sent a fix yesterday, addressing various mips build failures.

I sent the patch on Feb 17, resent the same one today

New regression as of today, haven't looked but seems trivial
